About MIMESIS

MIMESIS is a four-player online co-op horror game that requires a microphone. Players explore a building, gather anything of value, and must reach a tram before midnight while monsters imitate teammates, creating constant doubt about who is real.

The game features dangerous rain after nightfall, a service station for buying and upgrading equipment, full controller support, and Steam Cloud. This Steam listing is for Windows and notes DualShock and DualSense controller support.

01 / THE GUIDE

Microphone Requirement

A microphone is mandatory for MIMESIS, enabling voice chat among the four participants. The developers note that communication is essential for coordinating trust and suspicion during play.

A headset or earphones is recommended for the best experience, helping each player hear teammates clearly while limiting background noise.

  • Test your microphone before starting a session to avoid delays.
  • Adjust volume levels so all players can hear each other clearly.

02 / THE GUIDE

Rain Threat

Rain becomes dangerous once night falls, and the tram is the only shelter after dark. Players must return before midnight to avoid exposure.

The contaminated rain forces teams to manage time carefully, balancing exploration with the need to reach safety before the clock strikes twelve. Take on too much rain, and the next monster might be you.

  • Watch the in-game clock and plan routes that keep you near the tram before night.
  • Prioritize returning to the tram when the sky darkens to avoid rain exposure.

Equipment Upgrades

Collecting valuables lets players access a service station where they can restore power and purchase upgrades. Stronger gear improves survival chances against monsters.

Upgrades are not free, so teams must weigh the value of pushing deeper for loot against the risk of missing the tram deadline.

  • Gather as many high-value items as possible before returning to the station.
  • Restore power at the station before buying upgrades to ensure they are available.

04 / THE GUIDE

Controller Support

The Steam listing advertises full controller support, including DualShock and DualSense devices, so players who prefer a gamepad can use one.

Steam Cloud is also listed, though the store page does not specify which game modes share progress across installations.

  • Confirm your controller is detected by Steam before joining a session.
  • Check Steam Cloud status after playing to confirm your progress is stored.

05 / THE GUIDE

Online Co-op Play

The title is built for four players connected online, emphasizing cooperation while monsters imitate friends. Teams must push past threats scattered throughout the building and haul findings safely back to the tram.

Trust is central; any teammate could be a monster, creating tension that shapes how players interact and move through the environment.

  • Maintain clear voice communication to identify suspicious behavior.
  • Observe teammates for abnormal actions that may indicate an impostor.
